Abstract: The present invention discloses a pancake-type bifilar winding module using a superconducting wire and a winding bobbin therefor. The pancake-type bifilar winding module includes (a) a bobbin having (i) a cylindrical main body having a wire insertion groove for winding a superconducting wire in a bifilar manner to have the least inductance, in which the wire insertion groove has a depth greater than the width of the superconducting wire and a radius of curvature greater than a predetermined value, and is structured to guide the superconducting wire from one side to another side of the body, and (ii) a cylindrical supporting base having at least one block fixing notch and being disposed under the main body, (b) the superconducting wire wound in a bifilar manner, maintaining a predetermined tension as it is disposed in the wire insertion groove of the bobbin and curved in the middle portion thereof in the longitudinal direction, and (c) a copper block serving as an electrical terminal, which is installed and fixed to the block fixing notch of the supporting base of the bobbin for joining the superconducting wire with a terminal portion, and joined with the superconducting wire while the superconducting wire maintains a predetermined tension.
